United States Patent O PROFILEELEMENT FOR HARNESS FRAMES Paolo Formenti, Carate Brianza (Milan), ItalyApplication June 27, 1951, Serial No. 233,784 Claims priority,application Italy June 23, 11950 4 Claims. (Cl. 13991) The presentinvention relates to a profiled metal element manufactured from a singlesheet metal piece for use in connection with heddle frames and the like.

It is one of the objects of the invention to provide means resulting ina reinforced profiled element having folded flange means which increasethe resistance to buckling, While permitting the use of a structure ofextremely light weight. Another object of the invention is to providemeans conducive to a profiled element of great strength with greatresistance to both static and dynamic loads, which is made from onepiece of sheet etal.

A further object of the invention resides in means affording anextremely economical profiled element which is easy to manufacure, whichis readily cut into a plurality of elements of any desirable size andwhich has great rigidity.

These and other objects and features will become apparent from thefollowing detailed description, reference being had to the drawing, inwhich preferred embodiments of the invention are illustrated.

Fig. 1 shows in perspective an element. embodying the invention.

Fig. 2 is a modified form of the invention schematically shown andsomewhat in perspective.

The profiled element of Fig. l is obtained from a single piece ofpressed, rolled, drawn sheet metal or the like, having its middle body Acorrugated in order to obtain the necessary strength and rigidity.Longitudinal sides or end pieces B of the sheet are so bent at rightangles to body A and upon themselves as to create two crosswiseextending, parallel planes constituting longitudinal-guides for thesliding hooks supporting the heddle carrying blades '(not shown). Theouter or end pieces 2 of the element are united to center body A onwhich they rest, by welding, for instance by electric welding or othersuitable fastening means.

The profiled element illustrated in Fig. 2 has a middle or intermediarybox shaped zone C in order to obtain the necessary rigidity of saidelement.

The box shaped portion is connected by means of end parts D to crossstrip-like parts E to thereby form the Thus according to the invention aprofiled element for use in heddle frames is provided which is formedfrom a single folded sheet metal, comprising'an intermediate body, andopposite T-shaped end pieces, saidint'erm'ediate body being providedwith at least one portion offset with respect to the longitudinal centerline passing through webs of said T-shaped end pieces, said T-shaped endpieces including each two web-forming strips substantially parallel toeach other and substantially coinciding with said center line,furthermore two flange-forming strips extending from said web-formingstrips in opposed direction to each other and substantiallyperpendicular to said longitudinal center line, at least one of said T-shaped end pieces being provided with a crossstrip interconnecting saidtwo flange-forming strips adjacent the outermost ends, saidflange-forming strips of said T-shaped end pieces extending in planessubstantially parallel to each other and perpendicular to the planepassing through said center line.

It is preferred that the other of the T-shaped end pieces is alsoprovided with a cross-strip interconnecting its flange-forming strips,one of said web-forming strips of said one T-shaped end piece beingpositioned in a plane different from that of the respective web-formingstrip of the other T-shaped end piece, said respective one webformingstrips of said T-shaped end pieces being oriented in oppositedirections.

Said one web-forming strip of said one T-shaped end piece extends abovethe plane passing through the longitudinal center line, the oneweb-forming strip of the other T-shaped end piece being positioned belowsaid plane.

The aforesaid intermediate body is preferably composed of two oifsetportions each spaced a predetermined distance from said longitudinalcenter line and substantially level with said outermost ends of saidflange-forming strips of said T-shaped end pieces;

Having thus described the invention, what is claimed as new and desiredto be secured by Letters Patent, is:

1. A profiled element for use in heddle frames comprising a singlefolded metal sheet provided with an intermediate body, and with oppositeT-shaped end pieces said intermediatebody being provided with at leastone portion ofiset with respect to the longitudinal center line passingthrough the webs of said r shaped. end pieces, said T-shaped end piecesincluding each two web-forming strip parts substantially parallel toeach other and posed direction to each other and substantiallyperpendicular to said longitudinal center line, at least one of saidT-shaped end pieces being provided with a flatcrossstrip partinterconnecting said two fiangerforming strip parts adjacent theoutermost ends thereof, said flange forming strip parts of said T shapedend pieces being in height substantially coextensive with said offsetportion and extending in planes substantially parallel to each other.

2. An element according to claim 1, wherein the other of said T shapedend pieces is also provided with a flat cross-strip interconnecting itsflange-forming strip parts, one of said web-forming strip parts of saidone T-shaped end piece being positioned in a plane different from thatof the respective Web-forming strip part of the other T-' shaped endpiece, said respective one Web-forming strip parts of saidT-shapedendpieces being oriented in opposite directions. V

3. An element according to claim 2, wherein said one 7 Web-forming strippart of said one T-shaped end piece extends above the plane passingthrough the longitudinal center line, the one web-forming strip part ofthe other T-shaped end piece being positioned below said plane.

4. An element according to claim l, wherein said intermediate body iscomposed of two offset parallel por- I tions each'spaced a predetermineddistancefrorn said Ion-f gitudinal center line and substantially levelwith said outermost ends of said flange-forming strip parts of said V oo 15 T-shaped end pieces. 7
